Ok, I stand corrected. So, perl or lua (or C of course; I should have limited my statement
to "interpreted languages").
I don't know lua, but it sounds worth investigating.
Now, the second-level reason why we are using mod_perl is of course perl itself, and the
very rich CPAN add-on module library which goes with it, and which of course you can
/combine/ with mod_perl to do interesting things.
Does lua have anything similar ? (not immediately evident as per the lua website)
Note : since this is a mod_perl list, and since I presume we'd all be happier if there was
more consciousness and more usage of mod_perl, how come mod_lua has its own dedicated page
*within* the Apache httpd documentation, but mod_perl does not ?
(There could at least be a stub leading to https://perl.apache.org/docs/2.0/index.html)
